Dropped

The Dropped event fires after the Dropping event (if not cancelled). It is fired when a RadListBoxItem is dropped over an HTML element which has id attribute set. It is not fired when you drop an item over another RadListBox/RadListBoxItem.

The event handler receives two parameters:

1. The instance of the listbox firing the event

2. An event arguments parameter containing the following properties:

• HtmlElementID - the ID of the target element which the item is dropped over.

• SourceDragItems - a collection of RadListBoxItems which were dropped

protected void RadListBox_Dropped(object sender, RadListBoxDroppedEventArgs e)
{
    if (TextBox1.ClientID == e.HtmlElementID)
    {
        TextBox1.Text = String.Empty;
        foreach (RadListBoxItem item in e.SourceDragItems)
        {
            TextBox1.Text += item.Text + ", \n";
        }
        if (TextBox1.Text.Length > 0)
            TextBox1.Text = TextBox1.Text.TrimEnd(new char[] { ',', ' ', '\n' });
    }
}       

Protected Sub RadListBox_Dropped(sender As Object, e As RadListBoxDroppedEventArgs)
    If TextBox1.ClientID = e.HtmlElementID Then
        TextBox1.Text = [String].Empty
        For Each item As RadListBoxItem In e.SourceDragItems
            TextBox1.Text += item.Text + ", " & vbLf
        Next
        If TextBox1.Text.Length > 0 Then
            TextBox1.Text = TextBox1.Text.TrimEnd(New Char() {","C, " "C, ControlChars.Lf})
        End If
    End If
End Sub
